What might link these
The age dependency ratio and rural population per GDP might be connected through factors like urbanization and economic development. A careful reader should consider that education levels could be a confounder, as they can influence both age dependency and economic productivity. The relationship could be driven by underlying demographic and economic shifts.
Why this is not proof of anything
This is a correlation across countries, not an experiment. It cannot show that either indicator causes the other, and both may simply follow a third thing. This correlation could mislead by implying a direct link between rural population and age dependency, when in fact it may be driven by other factors like urbanization and economic development.
The second figure above repeats the measurement with national population and income held constant. It is the more conservative number: a relationship that largely disappears there was mostly telling you that larger, richer countries have more of most things.
How this was measured
Both indicators were ranked across every country reporting each, and the two rankings compared — ranks rather than raw values, because a handful of very large countries can otherwise manufacture a relationship on their own. The calculation is arithmetic over figures already published on this site; the commentary above is drafted from the two indicator names and the resulting coefficients.
